Galaxy groups are a key environment for studies of feedback processes, galaxyevolution and structure formation, but biases in current optical or X-rayselected samples hamper these efforts. We defined a complete optically-selectedsample of 53 nearby groups suitable for X-ray and radio follow-up, and recentlypublished a study of the X-ray properties and role of AGN feedback in the richer26-group subsample. We now propose to observe the 17 groups needed to completethe full sample. In combination with our completed CO and multi-band radiosurveys, these observations will allow detailed studies of the gas content,physical properties, and feedback history of an unbiased sample of groups, andsignificantly improve our understanding of the mass distribution of the local volume.

The European Space Agencys (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESAs second cornerstone of the Horizon 2000 Science Programme. It carries 3 high throughput X-ray telescopes with an unprecedented effective area, and an optical monitor, the first flown on a X-ray observatory. The large collecting area and ability to make long uninterrupted exposures provide highly sensitive observations. Since Earths atmosphere blocks out all X-rays, only a telescope in space can detect and study celestial X-ray sources. The XMM-Newton mission is helping scientists to solve a number of cosmic mysteries, ranging from the enigmatic black holes to the origins of the Universe itself. Observing time on XMM-Newton is being made available to the scientific community, applying for observational periods on a competitive basis.
